These patches seem to work except that the quoting of Subject field 
works only if user types a non-Ascii text to the "What subject should 
the initial email start with?" prompt. If she changes the subject in 
editor it won't be rfc2047-quoted.

Thank you anyway, I think we're going to right direction. I think 'git 
send-mail --compose' is nice way to produce introductory message to 
patch series. If --compose doesn't support MIME encoding reasonable 
way, user may have to write and send intro message with real MUA and 
find out the Message-Id for correct In-Reply-To field for the actual 
patch series.

E-mail agents KMail and Mutt have setting for preferred encodings for 
outgoing mail. It's a list of encodings, 
like "us-ascii,iso-8859-1,utf-8". The first one that fits (including 
From, To, Cc, Subject, the body, ...?) is used, so there is some kind 
of detection of content after the message has been composed.

If portable content encoding detection is difficult or considered 
unnecessary, then I think a documented configurable option is fine 
(UTF-8 by default).
